Example 1

As shown in fig. 1, the present embodiment provides a fluid pipeline switching device 5, which includes a body, and a fluid inlet 521 and a fluid outlet are provided on the body, so as to allow fluid to enter and exit. For on-off control of the fluid inlet 521 and the fluid outlet, a swinging member 54 is further rotatably disposed in the body, and the swinging member 54 can swing within a certain angle, so that the swinging member 54 can selectively open or block the fluid outlet, thereby realizing on-off control of the fluid outlet. The swing piece 54 is provided with a first magnetic piece 561, the body is provided with a second magnetic piece 562, the second magnetic piece 562 can be magnetically matched with the first magnetic piece 561, and the swing piece 54 is pushed to swing by applying magnetic acting force to the first magnetic piece 561, so that the on-off control of a fluid outlet is realized.

In this embodiment, the swing of the swing member 54 is realized by the magnetic force between the two magnetic members, so that the control is more convenient, and compared with the electromagnetic valve, the fluid pipeline switching device 5 in this embodiment has a simpler structure and low cost.

The magnetic members are configured to generate a magnetic field or to be attracted by the magnetic field, so that a magnetic force can be generated between the first magnetic member 561 and the second magnetic member 562.

In this embodiment, the second magnetic member 562 may be a magnet capable of generating a magnetic field, for example, may be a permanent magnet, and the first magnetic member 561 may be attracted by the magnet, so that the first magnetic member 561 drives the swinging member 54 to swing when being attracted by the second magnetic member 562, thereby opening or shielding the fluid outlet.

Illustratively, the first magnetic member 561 may be made of a ferromagnetic material such as iron, cobalt, nickel, etc., that is attracted to the magnet, and the first magnetic member 561 may also be a magnet having a polarity opposite to that of the second magnetic member 562.

In other embodiments, the first magnetic member 561 may be repelled by the second magnetic member 562, and the swinging member 54 may be driven to swing by the repulsive force of the second magnetic member 562.

Illustratively, the position of the oscillating member 54 when the first magnetic member 561 is attracted by the second magnetic member 562 is taken as a first position a where the fluid outlet is open and communication is established between the fluid outlet and the fluid inlet 521. When the first magnetic member 561 is not attracted by the second magnetic member 562, the position of the oscillating member 54 is the second position b, and when the oscillating member 54 is located at the second position b, the fluid outlet is blocked, and the fluid inlet 521 is not communicated with the fluid outlet. When the first magnetic element 561 is not attracted by the second magnetic element 562, the first magnetic element 561 is not subjected to magnetic force any more, in order to enable the swinging element 54 to swing automatically to the second position b, the fluid pipeline switching device 5 further comprises a reset element, the reset element can drive the swinging element 54 to rotate, and the direction of the reset element is opposite to the direction of the force applied by the second magnetic element 562 to the swinging element 54, so that when the second magnetic element 562 is not attracted to the first magnetic element 561 any more, the swinging element 54 can swing to the second position b under the action of the reset element to shield the fluid outlet.

Illustratively, the reset element may be a third magnetic element capable of exerting a magnetic force on the first magnetic element 561 such that the first magnetic element 561 moves to the second position b under the magnetic force exerted by the third magnetic element when not attracted by the second magnetic element 562.

In order to avoid the third magnetic element from affecting the effect of the second magnetic element 562 on the first magnetic element 561, the force applied by the third magnetic element on the first magnetic element 561 may be smaller than the force applied by the second magnetic element 562 on the first magnetic element 561, such that the magnetic force applied by the third magnetic element on the first magnetic element 561 can be resisted when the second magnetic element 562 attracts the first magnetic element 561.

The restoring member may be a spring, where one end of the spring is connected to the body and the other end is connected to the oscillating member 54, and when the second magnetic member 562 attracts the first magnetic member 561, the oscillating member 54 will rotate to the first position a against the force of the spring.

The spring may be a tension spring or a compression spring, or may be a torsion spring, for example, and the torsion spring may be disposed on a rotation shaft 55 of the swing member 54 connected to the body.

In order to enable the second magnetic member 562 to selectively attract or not attract the first magnetic member 561, the second magnetic member 562 may be movably disposed on the body. When the fluid outlet needs to be communicated with the fluid inlet 521, the second magnetic member 562 moves to an adsorption position close to the first magnetic member 561 relative to the body, so that the first magnetic member 561 can receive the magnetic adsorption force; when the fluid outlet and the fluid inlet 521 need to be disconnected, the second magnetic member 562 moves to a release position away from the first magnetic member 561 relative to the body, such that the first magnetic member 561 is no longer subject to the magnetic attraction force of the second magnetic member 562, and the swinging member 54 moves to the second position b under the action of the restoring member.

Illustratively, second magnetic element 562 is movable relative to the body and is disposed at any point between the suction position and the suction release position to adjust the magnetic force of second magnetic element 562 on first magnetic element 561, thereby adjusting the opening of the fluid outlet.

Specifically, the fluid pipeline switching apparatus 5 further includes a driving component 563, where the driving component 563 is disposed on the body, and an output end of the driving component 563 is connected to the second magnetic member 562 to drive the second magnetic member 562 to move between the adsorbing position and the desorbing position.

For example, the driving assembly 563 may be a linear motor, and an output rod of the linear motor is connected to the second magnetic member 562 for driving the second magnetic member 562 to move so as to move the second magnetic member 562 between the suction position and the release position.

Alternatively, the driving assembly 563 may be a cylinder, or may be other structures, so long as the second magnetic member 562 can be moved between the suction position and the suction release position.

In this embodiment, the second magnetic member 562 is located at the outer side of the body, so that on one hand, the inner space of the body can be increased, and on the other hand, the second magnetic member 562 is prevented from contacting with the fluid in the body, which is beneficial to protecting the second magnetic member 562 and prolonging the service life of the fluid pipeline switching device 5.

In order to improve the sealing performance of the fluid line switching device 5, the body includes a sealing sleeve 51, a first connection pipe 52 and a second connection pipe 53. The sealing sleeve 51 is made of elastic material, has certain elasticity and flexibility, one end of the sealing sleeve 51 is sleeved outside the first connecting pipe 52, a pipe orifice of the first connecting pipe 52 forms a fluid inlet 521, the other end of the sealing sleeve 51 is sleeved outside the second connecting pipe 53, and a pipe orifice of the second connecting pipe 53 forms a fluid outlet. The sealing sleeve 51 has elasticity, so that the sealing sleeve 51 can be in sealing connection with the first connecting pipe 52 and the second connecting pipe 53, and the tightness of the body is improved.

Illustratively, the sealing sleeve 51 and the first connecting pipe 52 can be fastened and fixed by the hoops 57, and the sealing sleeve 51 and the second connecting pipe 53 can also be fastened and fixed by the hoops 57, so that the sealing sleeve 51 is prevented from being separated from the first connecting pipe 52 and the second connecting pipe 53.

Illustratively, the swinging member 54 may be rotatably connected to the inner wall of the first connecting tube 52 by the rotation shaft 55, and the swinging member 54 is connected to the rigid first connecting tube 52, so that the fixing effect and stability of the swinging member 54 can be improved.

In this embodiment, the swinging member 54 includes a rotating portion 542 and a shielding portion 541, the rotating portion 542 is of a rigid structure, and the rotating portion 542 is connected to the inner wall of the first connecting tube 52 through the rotating shaft 55, so that the resistance received when the rotating portion 542 rotates is small, and the magnitude of the magnetic force required for driving the swinging member 54 to rotate can be reduced. One end of the rotating portion 542 is provided with a first magnetic member 561, and the other end is connected to the rotating portion 542. The rotating portion 542 drives the shielding portion 541 to rotate, so that the shielding portion 541 can shield the fluid outlet or open the fluid outlet. To enhance the shielding effect of the shielding portion 541, the shielding portion 541 can completely cover the fluid outlet.

Optionally, the shielding portion 541 and the rotating portion 542 may be elastically connected, so that an included angle between the shielding portion 541 and the rotating portion 542 may be adjustable, so that the shielding portion 541 may better contact with an inner wall of the body in which the fluid outlet is disposed, thereby improving the sealing effect.

Illustratively, the connection location between the blocking portion 541 and the rotating portion 542 may be made of an elastic material, such as rubber or silicone.

In this embodiment, two fluid outlets, i.e. the first fluid outlet 531 and the second fluid outlet 532, are disposed on the second connecting tube 53 for convenience of description, so that the fluid pipeline switching device 5 can realize split flow.

Illustratively, at least one of the first fluid outlet 531 and the second fluid outlet 532 may be disposed on a swing locus of the blocking portion 541 in the swing member 54 such that the blocking portion 541 can selectively block at least one of the first fluid outlet 531 and the second fluid outlet 532 by swinging.

Specifically, the swinging member 54 swings within the body, there may be two states, one to block one of the first fluid outlet 531 and the second fluid outlet 532, so that one of the first fluid outlet 531 and the second fluid outlet 532 communicates with the fluid inlet 521, and the other is cut off from the fluid inlet 521; the other is that the oscillating member 54 does not block both the first fluid outlet 531 and the second fluid outlet 532, so that both the first fluid outlet 531 and the second fluid outlet 532 communicate with the fluid inlet 521.

It should be noted that, in the first state, the swinging member 54 may be capable of shielding only one of the first fluid outlet 531 and the second fluid outlet 532 by swinging, and the other of the first fluid outlet 531 and the second fluid outlet 532 is always kept in communication with the fluid inlet 521; the oscillating member 54 may also selectively block the first fluid outlet 531 or the second fluid outlet 532, and at this time, the first fluid outlet 531 and the second fluid outlet 532 are both located on the oscillation locus of the blocking portion 541.

In order to further improve the tightness of the blocked fluid outlet, the oscillating piece 54 may abut against the inner wall of the sealing sleeve 51, which enables a sealing connection between the oscillating piece 54 and the sealing sleeve 51, thereby better cutting off the blocked fluid outlet from the fluid inlet 521. It should be noted that the abutment of the oscillating member 54 with the sealing sleeve 51 does not affect the oscillation of the oscillating member 54 within the sealing sleeve 51.

Taking the position shown in fig. 1 as an example, when the oscillating member 54 is in the second position b, the oscillating member 54 blocks the second fluid outlet 532, the second fluid outlet 532 is disconnected from the fluid inlet 521, and the first fluid outlet 531 is in communication with the fluid inlet 521. When the oscillating member 54 is in the first position a, the oscillating member 54 does not block the first and second fluid outlets 531, 532, and both the first and second fluid outlets 531, 532 are in communication with the fluid inlet 521. As the oscillating member 54 continues to rotate counterclockwise as viewed in fig. 1, the oscillating member 54 may rotate to a third position (not shown) that blocks the first fluid outlet 531 such that the first fluid outlet 531 is disconnected from the fluid inlet 521 and the second fluid outlet 532 is in communication with the fluid inlet 521.

In order to ensure that when the swing member 54 is located at the first position a, the first fluid outlet 531 and the second fluid outlet 532 can both communicate with the fluid inlet 521, the rotating portion 542 is further provided with a communication port 5421, and the communication port 5421 will communicate with two chambers separated by the rotating portion 542 in the body, so that both chambers can communicate with the fluid inlet 521.

In other embodiments, the fluid outlet may also be provided with one, three or more.

Example two

The present embodiment provides a fluid conduit switching device, which is different from the first embodiment in that the second magnetic member 562 is a soft magnetic body, and may be an electromagnet. The electromagnet can adsorb and desorb the first magnetic element 561 by powering on and off, thereby facilitating the control of the swing element 54.

Further, the magnetic poles of the second magnetic member 562 are adjustable so that the second magnetic member 562 can selectively attract the first magnetic member 561 or repel the first magnetic member 561 as desired. On this basis, the swinging member 54 can be moved between the position where the fluid outlet is blocked and the position where the fluid outlet is not blocked, without providing a reset member. The electromagnet can change the magnetic pole by controlling the direction of the current in the lead, thereby realizing the adjustment of the magnetic pole.

Optionally, the magnetic force of the second magnetic member 562 is adjustable to adjust the magnetic force applied by the second magnetic member 562 to the first magnetic member 561, so as to adjust the rotation angle of the oscillating member 54, and thus the opening of the fluid outlet. Specifically, second magnetic element 562 may adjust the magnitude of magnetic force by varying the magnitude of the current therein.
